{"doi":"10.1101/2020.03.24.006775","title":"The mouse cortico-tectal projectome","abstract":"SUMMARY The superior colliculus (SC) is a midbrain structure that receives diverse and robust cortical inputs to drive a range of cognitive and sensorimotor behaviors. However, it remains unclear how descending cortical inputs arising from higher-order associative areas coordinate with SC sensorimotor networks to influence its outputs. In this study, we constructed a comprehensive map of all cortico-tectal projections and identified four collicular zones with differential cortical inputs: medial (SC.m), centromedial (SC.cm), centrolateral (SC.cl) and lateral (SC.l). Computational analyses revealed that cortico-tectal projections are organized as multiple subnetworks that are consistent with previously identified cortico-cortical and cortico-striatal subnetworks. Furthermore, we delineated the brain-wide input/output organization of each collicular zone and described a subset of their constituent neuronal cell types based on distinct connectional and morphological features. Altogether, this work provides a novel structural foundation for the integrative role of the SC in controlling cognition, orientation, and other sensorimotor behaviors.","journal":"bioRxiv (Cold Spring Harbor Laboratory)","year":2020,"id":122026,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":5,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.8423,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":480851,"name":"Michael S.
